Download and install Windows 10 without using Windows Update Kicking off the consumer-focused Windows 10 event in Redmond on Tuesday, January 21, Microsoft operating system chief Terry Myerson announced that current users of Windows 7, Windows 8.1, and Windows Phone 8.1 will be able to upgrade to the new operating system for free as long as they do so within one year of Windows 10’s launch. Once you’ve claimed the upgrade, it’s permanent, and Microsoft will keep you updated for the supported lifetime of the device.

How to reserve Windows 10 on Windows 7 and 8.1
If you’re worried about missing your chance to download Windows 10 on July 29, don’t be. For one, you can always join the Windows Insider program, allowing you to download a preview copy of the OS and try out the new features as they’re tweaked and polished ahead of the launch.
Otherwise, you should be receiving a popup notification that’s triggered by the latest updates to Windows 7 and Windows 8.1. You’ll have the option of clicking on the popup to trigger the reservation process and ensure that your PC downloads the Windows 10 update, which will be free for up to a year after it launches. Interestingly, the updates will also scan your PC and alert you to any possible problems that you might have—such as incompatible hardware or services—when the upgrade kicks off. In all, the upgrade will total 3GB, Microsoft’s update says.
Once you’ve completed the process, though, relax! You can be sure you’ll have a brand new copy of Windows 10 running on your PC just as soon as everyone else does.
